What is Linux?

Linux is an open-source operating system. Like other operating systems, it connects applications to hardware. However, Linux runs on top of another OS, using an allotted amount of resources from the computer’s total resources to support itself. Many distributions, or distros, of Linux are derived from other major Linux distributions such as RedHat, Debian, and Ubuntu, so functionality can vary between different distros. The majority of Linux distros also use a command-line interface. This means that the user gives the OS instructions by typing commands in rather than relying on graphics.

Why Use Linux?

Linux is the go-to OS for cybersecurity. Even though it is less straightforward than graphic-based OSes, it is optimized for security. It gives users control over entire systems with options that they can micro-manage, such as users and groups, file permissions, etc. Linux is also used for offensive security. Linux can be used to exploit systems and devices and establish secure connections.

In this course, you will learn the very basics of how to use Linux and why these actions are important. Let’s begin!
